J. J. CORN SEAM Filed April 10, 1935 INVENTOR Julius J. Corn ATTORNEY-5Patented July 20, 1937 OFFIQE 1 Claim.

My invention relates to a means for uniting two pieces of fabric as by aseam, and relates specifically to fabrics of light weight and extremefineness, particularly such fabrics as are used in 5 the making offeminine undergarments, etc.

In connection with uniting two pieces of fabric in the forming of suchgarments, it is important that the seam or line of joining be as trimand neat as is possible consistent with strength of 1 the joining. Thesmaller the seam; i. e., the less bulky, the lesser is the discomfortengendered by contact of the body of the wearer against said seam.

It is the main object of my invention to provide 15 a seam or a joiningbetween two pieces of fabric, which will be simple and easy to make,which will be neat in finish and appearance, and which will causeminimum discomfort to the wearer.

It is a further object of my invention to provide 20 a seam or joiningbetween two pieces of fabric secured by a plurality of stitchings, oneof which is linear, and another of which is circular.

It is a further object of my invention to provide a seam or joiningbetween two pieces of fabric 25 secured by a plurality of stitchings oneof which is completely enclosed within another thereof, and out ofcontact therewith.

It is a further object of my invention to provide a seam or joiningbetween two pieces of 30 fabric with a plurality of stitchings, one ofwhich is linear, and another of which is circular; the

linear stitch being completely enclosed within the circular stitch, andout of contact therewith.

Further objects of my invention will in part be apparent from thefollowing description, and in part be specifically pointed outhereinbelow, where I describe the seam of my invention and making thesame. It is to be understood that my invention is not limited solely tothe precise 40 embodiment which I show and describe, but same includesany changes or departures therefrom coming within the scope'of theappended claim.

In the drawing annexed hereto and made a part hereof,

45 Fig. 1 is a perspective of two pieces of fabric disposed as in thefirst stage of the process whereby my new and improved seam is made;

Fig. 2 is a similar view of two pieces of fabric after the completion ofthe final operation; and

50 Fig. 3 is a section through a seam or joining of my invention.

The pieces of fabric l0 and I2 to be joined are disposed one on top ofthe other, with their respective edges M and I8 substantially aligned,and are securedtogether at !8 by a single, simple line of stitching 20disposed parallel to edges l4,

l and as close thereto as is possible with the 5 particular fabricsbeing joined. Securing the pieces to be joined by this straight-line(linear) stitching is the first step in the method by which my improvedseam is formed, and results in the uniting, by an edge thereof, of thesuperposed 10 fabrics.

The united edges l4, it are then rolled against the body of one of thepieces, either by hand, or mechanically, into a head 22. Optionally,instead of rolling, edges M, l 6 may be folded over several times toform this bead. There. is no limitation on the amount of rolling, ornumber of folds, except that the bead must be comparatively small, trimand neat to avoid causing discomfort by reason of excess bulk.

The formation of bead 22 is a second step in my method, and after thishas been completed, the final step is undertaken, which consists insewing a spiral or whip stitch 2A completely around and about bead 22and along its full length. 25

The bead 22 between the two pieces, is completely enveloped by thecircularly spiral stitch 2 which may be applied by hand, or machinesewn. The first line of stitching 2B is completely hidden inside bead22, and all that is visible in the completed seam is spiral or Whipstitch 24. A double safeguard is thus provided against opening of theseam. Primarily, stitch 24 will serve to keep the joined piecestogether, but in the event stitch 24 becomes loose, or the threadbreaks, linear stitch 20 will secondarily keep the pieces from pullingapart.

Having now described my invention, what I claim and desire to secure byLetters Patent is:

A seam uniting two pieces of material comprising a bead substantiallycircular in cross section in the center of which are disposed thealigned rolled up edges of the pieces to be joined, said pieces beingsecured together inside said bead by a line of stitching adjacent saidedges, and a line of stitching running spirally around said bead andalong its length, said spiral stitching confining the bead therewithinand keeping the inner stitching completely enclosed within the bead.
